2-3 days ago (around upgrade?), I noticed that all my Dropbox files and all my Drive files had become merged into their respective root directories (plus maxing out on storage.)
I uninstalled Insync, spent hours separating out the two and reinstalled Insync hope to have the email@example.com folder back in my Dropbox folder as has been the case for the past 2 years. Sadly, Dropbox and Drive became confused again and started sharing the same files and folders.
Attempting to change the Insync folder destination caused Insync to copy/move all my Dropbox files to the new location.
Why is Insync looking at parent directories and not just the firstname.lastname@example.org files for connecting to Drive?
Uninstalling Insync until this issues are resolved.
